Notes:

1. The rated current as listed is either the saturation current or the heating current depending

on which value is lower.

2. The nominal DCR is measured from point a to point b , as shown below on the mechanical

drawing.

3. The saturation current is the typical current which causes the inductance to drop by 20% at the

stated ambient temperatures (25°C and 100°C). This current is determined by placing the

component in the specified ambient environment and applying a short duration pulse current

(to eliminate self- heating effects) to the component.

4. The heating current is the DC current which causes the part temperature to increase by

approximately 40°C.

5. In high volt*time applications, additional heating in the component can occur due

to core losses in the inductor which may necessitate derating the current in order to

limit the temperature rise of the component. To determine the approximate total

losses (or temperature rise) for a given application, the core loss and temperature

rise curves can be used.

6. Optional Tape & Reel package can be ordered by adding a “T” suffix to the part

number (i.e. PA3146.211HL becomes PA3146.211HLT). Pulse complies to industry

standard tape and reel specification EIA481. The tape and reel for this product has a

width (W=24mm), pitch (Po=16.0mm) and depth (Ko=7.8mm).

7. The temperature of the component (ambient plus temperature rise) must be within

the stated operating temperature range.
